Abstract

PURPOSE: A tire for a vehicle with improved kerfs is provided to uniformly maintain a distance between both side walls of a kerf. CONSTITUTION: A tire for a vehicle with improved kerfs comprises a tread, a sidewall, and a bead part. Blocks(1) are formed on the grounding surface of the tread. Kerfs(2) are formed in the blocks. Protrusions(3,4), downward inclined, are formed on both wall surfaces(21,22) of the kerfs. The inclined direction of the protrusions that are formed on one surface of the kerfs is different from the inclined direction of the protrusions formed on the other surface of the kerfs.

Description

커프를 개량한 자동차용 타이어{Vehicle tire improved kerf}Automotive tire improved kerf {Vehicle tire improved kerf}

자동차용 타이어의 접지면에는 트랙션(Traction) 및 제동력을 향상시키기 위하여 커프(Kerf)를 형성시키게 된다. 그런데 이러한 커프는 일반적으로 1mm 정도의 세폭을 가지게 형성되어 있는 바 실제 주행시에는 세폭으로 이격된 양 측벽이 서로 만나게 될 가능성이 높다. 따라서 설계 시 고려되었던 커프 측벽간 간격을 유지하기 힘들다. A kerf may be formed on the ground surface of the tire for the vehicle to improve traction and braking force. However, these cuffs are generally formed to have a width of about 1 mm, and in actual driving, two side walls spaced apart from each other are likely to meet each other. Therefore, it is difficult to maintain the gap between the cuff sidewalls considered in the design.

그리하여 본 발명자는 주행 중에도 커프가 그 이격되는 폭을 그대로 유지하게 하기 위하여 커프의 내벽에 돌조(突條 ;돌출기둥)로 되는 세파레터(Separator)를 설치하여서 되는 타이어를 제공하는 바, 커프의 내벽에 돌출부를 형성시켜서 되는 종래의 타이어들에 관하여 조사를 한 결과, 아래와 같은 선행기술을 알게 되었다.Thus, the present inventors provide a tire provided with a separator formed as a protrusion on the inner wall of the cuff so that the cuff maintains the spaced apart space while running, and the inner wall of the cuff is provided. As a result of investigating the conventional tires formed by forming protrusions on them, the following prior art was found.

공개번호 제10-2006-0131499호는 커프를 형성시키기 위한 커프 성형용 블레이드를 제공함에 있어서, 소정 두께를 가지는 판상의 사각형이고, 일측면에 제 1 홈을 형성시키고, 상기 제 1 홈과 수직이면서 연통되게 제 2 홈을 형성시키는 것을 특징으로 하는 커프블레이드를 제공한 바 있다. 그러나, 이는 커프블레이드 자체를 절곡시켜서 된 것으로 주행시 커프의 폭이 일정하게 하려고 하는 본 발명의 목적을 달성할 수 있게 하는 것이 아니다. 즉, 이 기술은 양측 벽이 서로 일정한 간격을 가지며 평행하게 형성되어 있어서 트랙션 또는 제동 응력을 받게 되면 커프의 양 측벽이 서로 접하여질 염려가 크다. Publication No. 10-2006-0131499 discloses a blade for forming a cuff for forming a cuff, which is a plate-shaped quadrangle having a predetermined thickness, forming a first groove on one side, and perpendicular to the first groove. There has been provided a cuff blade, characterized in that to form a second groove in communication. However, this is because the cuff blades themselves are bent, and this does not allow the object of the present invention to achieve a constant width of the cuff during driving. In other words, this technique is that both sides of the wall are formed in parallel with a constant distance from each other, when the traction or braking stress is applied, both side walls of the cuff are likely to contact each other.

공개번호 제10-2006-0102015는 커프의 일측벽에 돌출된 반구돌기를 형성시키고 타측벽엔 반구홈소켓이 형성되어, 일측으로 코너링시 커프가 밀릴 때 반구돌기가 반구소켓홈에 삽입되어 그립력(Grip force)이 향상되므로 커프에 횡방향으로 응력이 작용되어도 블록과 블록이 분리되지 않고 일체로 움직이므로 블록의 강성이 약화되지 않게 하여서 되는 타이어를 제공한 바 있다. 그러나, 이 또한 양 측벽이 양측 벽이 서로 일정한 간격을 가지며 평행하게 형성되어 있어서 트랙션 또는 제동 응력을 받게 되면 커프의 양 측벽이 서로 접하여질 염려가 크다. Publication No. 10-2006-0102015 forms a hemisphere protrusion protruding on one side wall of the cuff and a hemisphere groove socket on the other side wall, and when the cuff is pushed when cornering to one side, the hemisphere protrusion is inserted into the hemisphere socket groove Since the grip force is improved, even when a stress is applied to the cuff, the tire is provided so that the block rigidity does not weaken because the block and the block move together without being separated. However, both sidewalls are formed in parallel with both walls at regular intervals, so that both sidewalls of the cuff are in contact with each other when subjected to traction or braking stress.

US 2007-281747는 커프의 바닥부에 록킹부(Locking Region)를 형성시킴으로써 록킹부가 커프 상부 벽 사이의 이격을 유도한다. 그러나, 이는 타이어가 마모되어 록킹부가 표면으로 들어나게되면 커프가 없어지는 셈이 되어 오히려 커프의 성능을 크게 저하시키는 결점이 있다.US 2007-281747 forms a locking region at the bottom of the cuff to induce a separation between the cuff top walls. However, this results in the cuff disappearing when the tire is worn and the locking portion is lifted to the surface, and rather, there is a drawback that the performance of the cuff is greatly reduced.

이에 본 발명은 주행 중, 타이어에 형성시킨 커프의 양 벽이 서로 달라 붙지 아니하게 하는 타이어를 제공하여 커프가 설계된 바 제 기능을 수행하게 하여야 하며, 특히 마모 후기에 있어서도 커프가 소기의 기능을 수행하게 하여야 한다는 과 제를 해결하고자 한다. 본 발명은 이에서 나아가, 주행 중 블록의 운동이 심하여 커프로 분할되는 양 벽 사이가 뒤틀어짐을 방지할 수 있게 하여야 한다는 과제를 해결하고자 한다.Accordingly, the present invention is to provide a tire so that both walls of the cuff formed on the tire do not stick to each other while driving, so that the cuff is designed to perform the bar function, especially in the late wear, the cuff performs the desired function. I want to solve the problem of having to. The present invention further aims to solve the problem that the movement of the block during driving is so severe that it is possible to prevent the warping between both walls divided into cuffs.

위와 같은 과제를 해결하기 위하여 본 발명은, 커프의 내벽에 상단으로부터 하향으로 향하여 길게 형성된 돌조를 설치하여서 된 타이어를 제공한다. 본 발명은 이에서 나아가 상기의 돌조를 마주보는 양벽에 각각 설치하되 마주 보는 양 벽의 돌조는 축방향 즉 수직 방향이 아닌 경사 방향으로 형성시켜서 된 타이어를 제공한다. 본 발명은 또한 양 벽에 설치된 돌조가 그 경사 방향을 달리하여 맞닿는 돌조가 X자 형으로 교차하도록 하여서 된 타이어를 제공한다. In order to solve the above problems, the present invention provides a tire formed by installing a protrusion formed on the inner wall of the cuff elongated downward from the upper end. The present invention further provides a tire which is installed on both walls facing each other, and the projections on both walls facing each other are formed in an inclined direction rather than in an axial direction, that is, in a vertical direction. The present invention also provides a tire in which the ridges provided on both walls differ in their inclined directions so that the ridges which abut against each other cross in an X shape.

본 발명은, 위의 각 돌조가 하단으로 갈수록 그 돌출 정도가 적어지도록 돌조의 직경을 점점 감소시켜서 된 타이어를 제공한다.The present invention provides a tire obtained by gradually reducing the diameter of the protrusions such that the protrusions of the above protrusions decrease toward the lower end thereof.

위와 같은 본 발명의 타이어는, 타이어가 노면과 접할 때 커프의 양 벽면에 형성된 돌조끼리 서로 접촉하게 되어 커프 양 측벽간의 거리를 일정하게 유지시킬 수 있는 효과가 있다. 또한 본 발명은 커프의 양 벽면에 형성시킨 돌조가 서로 맞물려 결착됨으로 블록의 뒤틀림을 방지할 수 있는 효과가 있다. 양 벽면 형성시킨 돌조는 커프의 하단으로 갈수록 반경이 작아져서 타이어가 마모됨에 따라 돌조의 크기가 점점 작아져 커프의 양벽 사이의 간격 확보량을 향상시키는 효과가 있다.  The tire of the present invention as described above, when the tire is in contact with the road surface, the stones formed on both wall surfaces of the cuff are in contact with each other there is an effect that can maintain a constant distance between the two side walls of the cuff. In addition, the present invention has an effect that can prevent the distortion of the block because the protrusions formed on both walls of the cuff are engaged with each other. The ridges formed on both walls have a radius that decreases toward the bottom of the cuff so that the size of the ridge gradually decreases as the tire is worn, thereby improving the amount of clearance between both walls of the cuff.

트레드와 트레드 양측의 사이드월 및 사이드월 양단의 비드부로 구성되고, 트레드부의 접지면에 블록(1)이 형성되고, 블록(1)에 커프(2)가 형성되고, 커프(2)의 벽면에 돌조가 형성된 자동차용 타이어에 있어서, 본 발명은, 커프(2)의 벽면에 형성된 돌조가, 커프(2)의 양 벽면(21, 22)에 커프(2)의 상단으로부터 축방향이 아닌, 즉, 수직 방향이 아닌, 하향 경사방향으로 각각 돌출 성형된 경사돌조(3, 4)인 것을 특징으로 하는 자동차용 타이어를 제공한다. The tread and the sidewalls on both sides of the tread and the bead portions at both ends of the tread, the block 1 is formed on the ground surface of the tread portion, the cuff 2 is formed on the block 1, and the wall surface of the cuff 2 is formed. In the automobile tire having a protrusion, the present invention provides that the protrusion formed on the wall surface of the cuff 2 is not in the axial direction from the upper end of the cuff 2 to both wall surfaces 21 and 22 of the cuff 2, that is, It provides a car tire, characterized in that the inclined protrusions (3, 4) protruded in the downward inclined direction, not the vertical direction.

본 발명은 또한, 마주보는 양 벽면(21, 22)에 설치된 위의 경사돌조(3, 4)가 서로 경사 방향을 달리하여 경사돌조(3)와 경사돌조(4)가 X자 형으로 만나 교차하게 형성된 타이어를 제공한다.In the present invention, the inclined protrusions 3 and 4 provided on the opposite wall surfaces 21 and 22 face each other in inclined directions so that the inclined protrusions 3 and the inclined protrusions 4 intersect in an X shape. To form a tire.

본 발명은, 위의 각 경사돌조(3, 4)가 하단으로 갈수록 그 돌출 정도가 적어지도록 경사돌조(3, 4)의 직경을 점점 감소시켜서 된 타이어를 제공한다.The present invention provides a tire in which the diameters of the inclined protrusions 3 and 4 are gradually reduced so that each of the above inclined protrusions 3 and 4 decreases toward the lower end thereof.
